Bill Wendling d01aee587f Update test to remove the 'unwind' instruction.

Bill Wendling d3c9d971e6 If we are extracting a basic block that ends in an invoke call, we must also 
extract the landing pad block. Otherwise, there will be a situation where the
invoke's unwind edge lands on a non-landing pad.

We also forbid the user from extracting the landing pad block by itself. Again,
this is not a valid transformation.

Akira Hatanaka 79738336a8 Make changes to avoid creating nested CALLSEQ_START/END constructs, which aren't 
yet legal according to comments in LegalizeDAG.cpp:227. 

Memcpy nodes created for copying byval arguments are inserted before
CALLSEQ_START.

The two failing tests reported in PR10876 pass after applying this patch.

Jim Grosbach 40700e0992 ARM asm parsing should handle pre-indexed writeback w/o immediate. 
For example, 'ldrb r9, [sp]!' is odd, but valid.

Benjamin Kramer 43a772eda1 Add a MachO-specific "mode" to llvm-objdump, that, if enabled, gathers additional information that are only available on MachO. 
- It can take FunctionStarts from a binary to find entry points more accurately.
- Symbol offsets in executables are correct now.

Nadav Rotem 7ae11279e9 When promoting integer vectors we often create ext-loads. This patch adds a 
dag-combine optimization to implement the ext-load efficiently (using shuffles).

For example the type <4 x i8> is stored in memory as i32, but it needs to
find its way into a <4 x i32> register. Previously we scalarized the memory
access, now we use shuffles.
